Preventing Incremental TAL Failures
To prevent incremental TAL failures, you must make copies of the following files before doing the update to preserve them during the update process:
• <InS_Home>/SW/System/Java/jre/security/cacerts
• <InS_Home>/SW/System/WildFly/standalone/configuration/ins.keystore
Copy these files to a safe area before the update, then restore them manually after the update. If you have a split or cluster configuration, preserve these files for all of the servers.
